Letters Patent No 93,590, dated August 10, 1869; antcdaterl August 6,1869.

IMPROVED GRAPPLE.

The Schedule referred to in these Letters Patent and makin part of thesame.

To all whom it may concern:

' Be it known that-I, J. H. Bnmron, of Thornbury,

Chester county, Pennsylvania, have invented ah Imscribe its constructionand operation, reference being had to the accompanying drawing, whichforms a part of this specification, and in which Figure 1 is 'a sideview of my improved hay-elevator, and

Figure 2 the same, as it appears after the discharge of a load frombetween its jaws.

Theapparatus consists of two metal bars, A and A, crossed and jointed ata, and so bent at their lower ends as to form curved jaws, between whicha mass of hay may be held, while the upper ends or arms of-the saidbars. are straight, and nearly parallel with each other when the jawsare closed, as shown in'fig. 1. The apparatus is suspended by a rope, B,which passes through slots at the upper ends of the arms A andA, andbeneath pulleys c 0, arranged to turn in the same, one end of the saidropebeing secured to some stationary object, and its opposite endpassing over a pulley,:v, and thence-to the point from which theapparatus is to be operated.

The cord F is secured to the jaw A, at the point (1, and passes around apulley, j; which is attached to the upper end of the bar A, there beingat the outer end of the said cord, a metal ring or eye, It, throughwhich the operating-rope passes, but the diameter of which is toocontracted to admit of the passage of the ball H.

The mndeofloading-the grapple with hay or othermaterial is apparent, thejaws being opened and forced downward into a mass of hay, and closingand grasping a portion of the mass, when the whole is raised by means ofthe Operating rope. 7

When the elevator and its load have been raised to r the required point,the ball H of the operating-rope passes beneath the pulleys -c c,and-strikes against the ring'k of the cord F, but cannot pass throughthe same, and as the ball continues to move toward the pulley as,carrying the ring and end of the cord F with it, thelatter will draw thejaw A, and upper end of the bar A toward each other, until the centre ofgravity of the apparatus becoming suddenly shifted, the jaws arecompletely opened, and the load discharged.- I claim as my invention,and desire to secure by Letters Patent- A cord, F,tconne cted to thejaws A A of a grapple,

and having a ring or eye, k, at its outer end, for the passage of theoperating-rope, all substantially as and
